SPRINT

Tap the screen, or press space (or any of A, D, Z, X, the arrows), to push the gauge up; it falls back all the time, faster as the race goes on. In the green you run flat out. In the red you stumble for a moment, so don't mash. Too low and you slow down. Every tap and every stride in the green costs stamina (the bar under the gauge); easing off below the green wins it back. Run the tank dry and you can't reach the green until a third of it is back, so pick where to ease off. A leg is worth 3 if you held the green for 80% of it, 1 for half. Your pace widens the green and raises your top speed, your physique makes the tank last; beat the rival to the line too.
